2024 AMG GT 53 4-Door – Anyone running 275/40R21 front on stock 21s? Pothole concerns

Hi everyone,

I’m looking for real-world feedback from other AMG GT 4-Door owners or just guys with tech knowledge, specifically GT 53.

Car details:

2024 Mercedes-AMG GT 53 4MATIC+ 4-Door
Factory 21″ AMG wheels
OEM sizes:
- Front: 275/35ZR21
- Rear: 315/30ZR21
AMG Ride Control+ suspension (fully stock, no lowering)

Reason for considering a change:
Roads where I live are rough with potholes, and I’m concerned about wheel damage with the very low-profile OEM tyres. I’m not chasing performance or stance — just more sidewall protection while keeping the car safe and reliable.

Size I’m considering:

Front: 275/40R21
Rear: 315/30R21 (stock rear)or 315/35/R31

I’m not trying change wheels i like the 21 rims, so no downgrade — just tyres on the factory 21″ rims.

Questions for those with experience:

Has anyone actually run 275/40R21 on the front of a GT 4-Door with AMG Ride Control+?
Any rubbing issues under compression, potholes, or full steering lock?
Any problems with ABS/ESP/4MATIC behavior or warning lights?
Dealer/warranty issues after upsizing the front only?

I know this size isn’t officially listed by Mercedes, so I’m specifically looking for real-world owner experience, not just tyre calculator theory.

Thanks in advance — appreciate any feedback or photos if you’ve tried something similar.
